How is coagulation achieved by electrophoresis?

Options

  1. AColloidal particles move towards oppositely charged electrodes and get discharged.
  2. BColloidal particles move towards similarly charged electrodes and get discharged.
  3. CColloidal particles move towards oppositely charged electrodes and acquire more charge.
  4. DColloidal particles move away from the electrodes and settle down.

Correct answer

A. Colloidal particles move towards oppositely charged electrodes and get discharged.

Step-by-step solution

The paragraph mentions that, in electrophoresis, colloidal particles move towards oppositely charged electrodes, get discharged, and precipitated.
